-USSR Bomb bigger than Tsar's Bomb- A reference exists in Spanish press before 1972, about a 200 MT Nuclear Weapon tested underground in their usual test place, Novaya Zemlya, including images of the cave it built. — Preceding unsigned comment added by 81.44.88.66 ( talk) 18:51, 20 May 2023 (UTC)

Farmbrough,

The original test was done in secrecy in the Soviet Union. NATO scientists measured the blast from afar, using seismic signals and other indications, and came up with 57 MT. After the Cold War, the writings of the Soviet scientists on the ground on the spot indicated a yield of 50 MT. Since they were there but we were not, their measurements are more valid. They knew how to do them, and so 50 MT is the official value. This error has been repeated several times, and the notes here in Talk get archived. And someone new steps up. 50 MT is the correct value. SkoreKeep ( talk) 14:55, 24 January 2016 (UTC)
Perhaps you would. However, the nformation was in documents that the CIA paid the Russian scientists to compile, and it wasn't released until after the end of the USSR. They wereon the site; NATO was not. SkoreKeep ( talk) 08:46, 30 October 2017 (UTC)

to trueUser:Altenmann reverted my referenced contribution https://en.wikipedia.org/?title=Tsar_Bomba&oldid=751339587 . I have reverted his revert and restored my changes on the grounds that all of the people making the statements were notable at the time, and that the reaction of people in power in the United States and abroad is important to understand how the world reacted to the nuclear test. I would hardly call the prime ministers of Norway, Canada, and the British foreign office "random politicians".

Comes Max Arosev with this chestnut: "The explosion was hot enough to induce third degree burns at distances of 100 km (62,14 mi). The flash of light was so bright that it was visible at a distance of 1,000 km (621,37 mi), despite cloudy skies. Tsar Bomba caused extensive environmental damage: the ground surface of the island was completely levelled, as were the rocks. Everything in the area was melted and blown away. [1]"
I decline on this for several reasons:
1. It is just about, if not entirely, cribbed from the CTBTO website.
2. This sort of over-blown unscientific "gee-whiz" stuff has followed the Tsar around for far too long. I have never seen any kind of scientific basis for any of these claims, or even an on-the-spot newspaper article, and I think that they're probably simple folklore. And that goes for the "windows shattered" in Finland, as well. If the effect was so unexpected, so one-of-a-kind, then credentials for each and every one should be able to allow them to stand as facts, or they should be dropped.
3. The Tsar was done in top secrecy by the politburo, but too many ears in other countries were listening. In that environment, who was going around measuring "visible at 1000 km"? How does one compare that to other similar occurrences? It sounds cool and trendy, but does anyone know of a similar factoid to be able to say, "Yeah, that really was a world buster, compared to (Tunguska, Krakatoa, ???)."?
4. I would normally give high marks to the ctbto website as reference material, but after reading this squib in the context of "Test that went wrong or caused unforseen damage" I really begin to wonder about whose POV is being expressed here. "Everything in the area was melted and blown away" is not quite the sort of analysis I'd expect from the world's expert in atomic explosion detection. Sukhoy Nos (translates as "Dry Nose") was never much of a travel destination in any case.
As a side note, use the CVT script to do your conversions. I want to know who it was that staked himself out at 621.37 miles in cloudy skies from the epicenter to get that measurement. It will also take care of that European comma, one way or the other. Also check spelling. Lastly, complete the reference.
If Mr. Arosev insists on using this, then I'm going to insist on a specific reference for each and every claim. Good luck with that. SkoreKeep ( talk) 20:59, 10 June 2017 (UTC)

This line was seen in the "Test" section: "...flown by Major Andrei Durnovtsev. Taking off from an airfield in the Coca Cola Peninsula, the release plane was accompanied..."
I don't think that the Coca Cola Peninsula is a real place unless I am sorely mistaken here. (Especially given that the Soviets would be unlikely to name a significant geographical feature after a capitalist American soda company)
I think it's supposed to be referring to the Kola Peninsula (where Murmansk is) and is a likely nearby area that also has a military airfield.
Again, if anyone can confirm whether or not a "Coca Cola Peninsula" existed, I'd appreciate it, but I find it highly unlikely to be anything other than The Kola. (I added a note next to the location) — Preceding unsigned comment added by 67.8.134.46 ( talk) 20:00, 7 September 2017 (UTC)

Comes 37.131.57.110 changing the size of the fireball (presumed maximum size) from 8 km to 4.6 km in diameter. Doing a quick search, I find everyone agreeing with the old number (or in some cases 5 km) and I think that probably is a case of some copycatting. I like the new number better, since the bomb exploded at 3-4 km high and the fireball did not reach the ground, possibly also due to some flattening by shockwave reflection. I note that captioned on a picture of the fireball is the figure 4.6 km, so, without some Russian expert to contradict it, I'm happy with the change. However, it would be nice if there was a solid reference for it.
[Minutes later...] Eh, was I fooled. The incidence in the picture caption was the change made. So I have nowhere else found that figure. Perhaps 37.131.57.110 would like to come forward, then, with a reference. SkoreKeep ( talk) 00:42, 3 August 2018 (UTC)

By any chance, does the specific aircraft that dropped the bomb - a Tu-95V - still exist somewhere? If not, does anyone know what happened to it? Elsquared ( talk) 18:06, 20 August 2020 (UTC)
The test dates were running out. Palliative measures were taken: increasing the drop height and turning on the afterburner of the aircraft engines after the bomb was dropped. At the same time, in the flight task for the aircraft crew, deliberately or erroneously (now it is difficult to say), an underestimated explosion power was indicated. The crew reported on the fulfillment of the combat mission to the chairman of the State Commission for Nuclear Testing, General N. I. Pavlov. After the official report, the commander of the crew, Lieutenant Colonel Martynenko (Hero of the Soviet Union, who received this title for testing nuclear warheads) explained to us what scoundrels we are, that we had underestimated the estimated power of the explosion. The essence was as follows: after the explosion, the light flux was so intense that the protective paint of the aircraft burned out, after the arrival of the first air shock wave, the aircraft received a large increase in speed (from 880 to 980 km / h), after which it fell into a deep rarefaction zone and “failed "At 800 m. The terse and gloomy Martynenko said that he thought" the wings of the plane will come off. " After examining the plane, we saw that the bottom was all black (instead of blindingly white before the flight), the skin was pressed down everywhere and the power set of wings and fuselage stood out brightly: stringers, ribs, frames. We understood what it was like for the crew at that unfortunate moment. We learned about the power of this explosion even before the plane arrived.
....
The commander of the 6th Air Force Directorate, Lieutenant General N.I. Sazhin immediately offered to send the damaged aircraft to the Air Force training center as a visual aid to the effects of a nuclear explosion on aviation equipment. So nothing is missing.

Recently, the Rosatom State Atomic Energy Corporation has released newly declassified footage of Tsar Bomba. The information in the video linked above should be incorporated into the article. — Preceding unsigned comment added by 192.245.87.15 ( talk) 13:44, 26 August 2020 (UTC)
Reference 36 (" Tsar Bomba's Blast Wave Orbited Earth Three Times in 1961". Pravda.ru. 24 September 2009. Retrieved 24 September 2009.) mentions the bomb being dropped from a height of 4500 meters: "The aircraft dropped the bomb within the territory of the range ground at the height of 4,500 meters.". I think this is faulty. This reference ([36]) is placed after the sentence: "The Tsar Bomba was the single most physically powerful device ever deployed on Earth."...But the particular reference doesn't seem to mention why it would be the single most powerfull device deployed.
The article currently mentions (without a reference): "The bomb was released two hours after takeoff from a height of 10,500 m (34,500 ft) on a test target within Sukhoy Nos."
Reference 22 ( http://www.nuclearweaponarchive.org/Russia/TsarBomba.html) mentions a drop height of 10,500 meters: "It was released at 10,500 meters, and made a parachute retarded descent to 4000 meters in 188 seconds before detonation."

(I am Russian speaking, I use machine translation; I am the editor of the article about Tsar Bomba on the Russian Wikipedia page). The story of the T-15 thermonuclear torpedo with a capacity of 100 megatons in 1952 is an unconfirmed fiction from an incompetent journalist from the TASS online edition of October 29, 2016, who wrote this article. For example, in the information contained in the article: http://bourabai.ru/adushkin/ch1_6.htm there is only information that the T-15 torpedo was planned with a caliber of 1550 mm, which at that time approximately corresponded to the original caliber. charge of the atomic bomb RDS-1, and then the caliber of "puffs" RDS-6, which were considered thermonuclear, and had a maximum explosion power of about 400 kilotons (the Tsar Bomba had a caliber of not 1550 mm, but more than 2000 mm, and there was no 100 megaton torpedo mention). For the first time, the idea of a torpedo with a capacity of 100 megatons was proposed only 10 years later, in 1962, by A.D. Sakharov after testing An-602, about which he writes in his book of memoirs. I propose to remove false information that has nothing to do with the article about the Tsar Bomb. (Russian Wikipedia has a separate article on the T-15 torpedo). Finder-nev -- Finder-nev ( talk) 11:38, 23 February 2021 (UTC)
My understanding of the nuclear weapon staging (understand that I'm not a weapons engineer; I got most of what I know from reading others) is that the first stage of a multistage device is the fission stage that supplies radiation and neutrons to the second stage which is a fusion device. If there is a third stage it is an additional fusion stage; examples of such weapons include the Tsar and the US B-41 bomb. Any fissioning tamper is not regarded as a "stage" by designers; it is a multi-functional component of most all nuclear weapons starting with the Trinity Gadget. All nuclear bomb stages other than the first are fusion stages.
Given this understanding there is lots of confusion in various parts of the article about the staging as well as the physical construction of the Tsar. I started to correct it from my understanding, but in at least one place the misunderstanding appears to be within a quoted Soviet document. I don't know whether that is a problem in a differing Russian interpretation of my understanding or an error in translation, but it needs to be either straightened out or an explanation written to guide the reader through all this. I'm certainly up for writing that if that is what is needed, but I need the quotation to be deemed correctly translated if that is indeed the problem.
User Finder-nev made some corrections to the quoted materials, so if it is a quote, that needs to be backed out as well, or at least reworded so as to be a paraphrase or interpretation of the quote. SkoreKeep ( talk) 21:59, 9 March 2021 (UTC)
A very controversial question about stages! After the well-known book “Brighter than a Thousand Suns”, written by R. Jung in 1958 based on the results of his investigation of the Manhattan Project, “dirty” thermonuclear munitions became commonly called FFF (Fission-Fusion-Fission) or three-stage (three-stage, or three-phase). However, this term is not correct. Almost all "FFF" refer to two-stage (two-phase) and differ only in the material of the tamper, which in "pure" FF (Fission-Fusion) ammunition can be made of non-fissile material (lead, tungsten, etc.), and in FFF (Fission-Fusion-Fission) from fissile material (uranium 238, thorium 232, or uranium 235, or plutonium 239, etc.). In multi-stage thermonuclear weapons, each stage is a complete separate nuclear or thermonuclear stage. In three-stage thermonuclear munitions, each stage is 3 separate nuclear and/or thermonuclear stages (charges). Usually in three-stage thermonuclear munitions, the first stage is a fission nuclear charge that emits X-ray radiation, which serves for the 2nd (small) fusion and 3rd (large fusion) stage radiation implosion. The second (“small” thermonuclear) stage fires next, after stage 1, and its X-ray radiation is used for further radiation implosion of the 3rd (“large” thermonuclear) stage.
In the AN-602 ("Tsar Bomba"), the 1st stage consisted of not one, but of 2 fission charges, the 2nd stage also consisted of not one, but of 2 "small" thermonuclear charges, but these 1st and 2nd stages were located symmetrically on both sides of the 3rd ("large" main thermonuclear) stage located in the center (the so-called "bifilar" scheme) for the AN-602 ("Tsar Bomba").
In the USSR, except for the RDS-202 and AN-602 ("Tsar Bomba"), such a scheme was never used again.
Finder-nev ( talk) 01:09, 16 April 2021 (UTC)
There are errors in the article that lead to confusion with the stages. Quote:
The test of such a complete three-stage 100 Mt bomb was rejected due to the extremely high level of radioactive contamination that would be caused by the fission reaction of large quantities of uranium-238 fission.[40] During the test, the bomb was used in a two-stage version. A. D. Sakharov, suggested using nuclear passive material instead of the uranium-238 in the secondary bomb module, which reduced the bomb's energy to 50 Mt, and, in addition to reducing the amount of radioactive fission products, avoided the fireball's contact with the Earth's surface, thus eliminating radioactive contamination of the soil and the distribution of large amounts of fallout into the atmosphere.[16]
In fact, the AN-602 ("Tsar Bomba") was not 2-stage, but 3-stage, only in the "dirty" 100 Mt version in stage 3, fissile material was used as a tamper - uranium-238 or natural uranium, and in In the “clean” 50 Mt version, a non-fissile material, lead, was used as a tamper.
PS: I myself have introduced some confusion into the discussion. I ask English-speaking editors to correct this error. -- Finder-nev ( talk) 16:51, 11 February 2022 (UTC)

Quote: Better source required | reason = Unable to verify the source. It is not known what this website is or who its author is. The "Bifilar" scheme does not make sense and will require two primary stages, as well as two sets of secondary ones. The use of two primary colors on each side was suggested as implausible during the Progressive event and should not be necessary. Date = March 2021

This text received from the participant of the event and his direct observer.
For the radiation implosion of such a large secondary (unit, block), module (a thermonuclear charge with a power of 50 megatons in TNT equivalent, the diameter of the main fusion unit was about 2 meters) a very high X-ray power is needed, which could only be produced by 2 thermonuclear charges (primary modules), for uniform implosion placed with on two opposite sides of the secondary module (i.e. symmetrically). Why exactly "thermonuclear" and not "nuclear" ones?
1). It doesn't matter which charge, nuclear or thermonuclear, is the source of X-rays for the secondary module. It is only important that this radiation is sufficient for effective radiation implosion of the used secondary module.
2). Nuclear charges have an explosion power, even with deuterium-tritium amplification, only a few tens of kilotons in TNT equivalent. (Even RDS-6s ("puff"), and even then had an explosion power of only 400 kilotons in TNT equivalent). And for effective radiation implosion of the Tsar Bomba secondary module, a design power of 2 x 750 kilotons in TNT equivalent was needed, which is about 10 times more than the "nuclear" charges could produce. Therefore, it was precisely "thermonuclear" charges that were used. In 3 authoritative sources of information it is written (links to which are given below) that 2 thermonuclear charges were used as the first stage of the bomb, and not one nuclear:

Hi all Wiki Authors,
With reference to the following sentence, in the second paragraph under the section 'Project Goals':
As an expression of the concept of nuclear deterrence adopted during the leadership of Georgy Malenkov and Nikita Khrushchev, the actual strategic situation in consideration to this concept, for the Soviet Union, as a consequence of the disequilibrium with regards to the Soviet Union vis-à-vis America's nuclear weapons possessions, to the favour of the latter, was that the creation of Tsar Bomba represented a necessitated bluff.
Appears to be an overly long and nonsensical way of saying the Soviet Union chose to go bigger to challenge the USA's more accurate deployment. I was going to change it to something I considered a little clearer, but after reading some of the conversations on how the English language should be structured in this thread, realised I was way out of my league on correct vocabulary.

convey the same meaning more clearly? JezGrove ( talk) 23:42, 13 November 2021 (UTC)Given the Soviet Union's actual strategic disadvantage vis-à-vis America's nuclear weapons possessions, foreign policy and propaganda considerations during the leaderships of Georgy Malenkov and Nikita Khrushchev made a response to the perceived US nuclear blackmail imperative. The creation of the Tsar Bomba represented a necessitated bluff in order to maintain the concept of nuclear deterrence.

The detonation was intended to be secret, but was detected by United States intelligence agencies, via a KC-135A aircraft (Operation SpeedLight)[11]
The fact that the explosion was secret is not true, since the USSR announced the upcoming test in advance. Criticism of the upcoming test followed at the UN, and in particular from the United States, due to the expected contamination of planet Earth with radionuclides. However, the US did not know the exact time of the upcoming test. -- Finder-nev ( talk) 17:14, 11 February 2022 (UTC)

The original test was done in secrecy in the Soviet Union. NATO scientists measured the blast from afar, using seismic signals and other indications, and came up with 57 MT. After the Cold War, the writings of the Soviet scientists on the ground on the spot indicated a yield of 50 MT. Since they were there but we were not, their measurements are more valid. They knew how to do them, and so 50 MT is the official value. This error has been repeated several times, and the notes here in Talk get archived. And someone new steps up. 50 MT is the correct value. SkoreKeep ( talk) 14:55, 24 January 2016 (UTC)

Comes Max Arosev with this chestnut: "The explosion was hot enough to induce third degree burns at distances of 100 km (62,14 mi). The flash of light was so bright that it was visible at a distance of 1,000 km (621,37 mi), despite cloudy skies. Tsar Bomba caused extensive environmental damage: the ground surface of the island was completely levelled, as were the rocks. Everything in the area was melted and blown away. [1]"
I decline on this for several reasons:
1. It is just about, if not entirely, cribbed from the CTBTO website.
2. This sort of over-blown unscientific "gee-whiz" stuff has followed the Tsar around for far too long. I have never seen any kind of scientific basis for any of these claims, or even an on-the-spot newspaper article, and I think that they're probably simple folklore. And that goes for the "windows shattered" in Finland, as well. If the effect was so unexpected, so one-of-a-kind, then credentials for each and every one should be able to allow them to stand as facts, or they should be dropped.
3. The Tsar was done in top secrecy by the politburo, but too many ears in other countries were listening. In that environment, who was going around measuring "visible at 1000 km"? How does one compare that to other similar occurrences? It sounds cool and trendy, but does anyone know of a similar factoid to be able to say, "Yeah, that really was a world buster, compared to (Tunguska, Krakatoa, ???)."?
4. I would normally give high marks to the ctbto website as reference material, but after reading this squib in the context of "Test that went wrong or caused unforseen damage" I really begin to wonder about whose POV is being expressed here. "Everything in the area was melted and blown away" is not quite the sort of analysis I'd expect from the world's expert in atomic explosion detection. Sukhoy Nos (translates as "Dry Nose") was never much of a travel destination in any case.
As a side note, use the CVT script to do your conversions. I want to know who it was that staked himself out at 621.37 miles in cloudy skies from the epicenter to get that measurement. It will also take care of that European comma, one way or the other. Also check spelling. Lastly, complete the reference.
If Mr. Arosev insists on using this, then I'm going to insist on a specific reference for each and every claim. Good luck with that. SkoreKeep ( talk) 20:59, 10 June 2017 (UTC)

This line was seen in the "Test" section: "...flown by Major Andrei Durnovtsev. Taking off from an airfield in the Coca Cola Peninsula, the release plane was accompanied..."
I don't think that the Coca Cola Peninsula is a real place unless I am sorely mistaken here. (Especially given that the Soviets would be unlikely to name a significant geographical feature after a capitalist American soda company)
I think it's supposed to be referring to the Kola Peninsula (where Murmansk is) and is a likely nearby area that also has a military airfield.

Comes 37.131.57.110 changing the size of the fireball (presumed maximum size) from 8 km to 4.6 km in diameter. Doing a quick search, I find everyone agreeing with the old number (or in some cases 5 km) and I think that probably is a case of some copycatting. I like the new number better, since the bomb exploded at 3-4 km high and the fireball did not reach the ground, possibly also due to some flattening by shockwave reflection. I note that captioned on a picture of the fireball is the figure 4.6 km, so, without some Russian expert to contradict it, I'm happy with the change. However, it would be nice if there was a solid reference for it.
[Minutes later...] Eh, was I fooled. The incidence in the picture caption was the change made. So I have nowhere else found that figure. Perhaps 37.131.57.110 would like to come forward, then, with a reference. SkoreKeep ( talk) 00:42, 3 August 2018 (UTC)

The test dates were running out. Palliative measures were taken: increasing the drop height and turning on the afterburner of the aircraft engines after the bomb was dropped. At the same time, in the flight task for the aircraft crew, deliberately or erroneously (now it is difficult to say), an underestimated explosion power was indicated. The crew reported on the fulfillment of the combat mission to the chairman of the State Commission for Nuclear Testing, General N. I. Pavlov. After the official report, the commander of the crew, Lieutenant Colonel Martynenko (Hero of the Soviet Union, who received this title for testing nuclear warheads) explained to us what scoundrels we are, that we had underestimated the estimated power of the explosion. The essence was as follows: after the explosion, the light flux was so intense that the protective paint of the aircraft burned out, after the arrival of the first air shock wave, the aircraft received a large increase in speed (from 880 to 980 km / h), after which it fell into a deep rarefaction zone and “failed "At 800 m. The terse and gloomy Martynenko said that he thought" the wings of the plane will come off. " After examining the plane, we saw that the bottom was all black (instead of blindingly white before the flight), the skin was pressed down everywhere and the power set of wings and fuselage stood out brightly: stringers, ribs, frames. We understood what it was like for the crew at that unfortunate moment. We learned about the power of this explosion even before the plane arrived.
....
The commander of the 6th Air Force Directorate, Lieutenant General N.I. Sazhin immediately offered to send the damaged aircraft to the Air Force training center as a visual aid to the effects of a nuclear explosion on aviation equipment. So nothing is missing.

Reference 36 (" Tsar Bomba's Blast Wave Orbited Earth Three Times in 1961". Pravda.ru. 24 September 2009.

I think this is faulty. This reference ([36]) is placed after the sentence: "The Tsar Bomba was the single most physically powerful device ever deployed on Earth."...But the particular reference doesn't seem to mention why it would be the single most powerfull device deployed.
The article currently mentions (without a reference): "The bomb was released two hours after takeoff from a height of 10,500 m (34,500 ft) on a test target within Sukhoy Nos."
Reference 22 ( http://www.nuclearweaponarchive.org/Russia/TsarBomba.html) mentions a drop height of 10,500 meters: "It was released at 10,500 meters, and made a parachute retarded descent to 4000 meters in 188 seconds before detonation."

(I am Russian speaking, I use machine translation; I am the editor of the article about Tsar Bomba on the Russian Wikipedia page). The story of the T-15 thermonuclear torpedo with a capacity of 100 megatons in 1952 is an unconfirmed fiction from an incompetent journalist from the TASS online edition of October 29, 2016, who wrote this article. For example, in the information contained in the article: http://bourabai.ru/adushkin/ch1_6.htm there is only information that the T-15 torpedo was planned with a caliber of 1550 mm, which at that time approximately corresponded to the original caliber. charge of the atomic bomb RDS-1, and then the caliber of "puffs" RDS-6, which were considered thermonuclear, and had a maximum explosion power of about 400 kilotons (the Tsar Bomba had a caliber of not 1550 mm, but more than 2000 mm, and there was no 100 megaton torpedo mention). For the first time, the idea of a torpedo with a capacity of 100 megatons was proposed only 10 years later, in 1962, by A.D. Sakharov after testing An-602, about which he writes in his book of memoirs. I propose to remove false information that has nothing to do with the article about the Tsar Bomb. (Russian Wikipedia has a separate article on the T-15 torpedo). Finder-nev -- Finder-nev ( talk) 11:38, 23 February 2021 (UTC)
My understanding of the nuclear weapon staging (understand that I'm not a weapons engineer; I got most of what I know from reading others) is that the first stage of a multistage device is the fission stage that supplies radiation and neutrons to the second stage which is a fusion device. If there is a third stage it is an additional fusion stage; examples of such weapons include the Tsar and the US B-41 bomb. Any fissioning tamper is not regarded as a "stage" by designers; it is a multi-functional component of most all nuclear weapons starting with the Trinity Gadget. All nuclear bomb stages other than the first are fusion stages.
Given this understanding there is lots of confusion in various parts of the article about the staging as well as the physical construction of the Tsar. I started to correct it from my understanding, but in at least one place the misunderstanding appears to be within a quoted Soviet document. I don't know whether that is a problem in a differing Russian interpretation of my understanding or an error in translation, but it needs to be either straightened out or an explanation written to guide the reader through all this. I'm certainly up for writing that if that is what is needed, but I need the quotation to be deemed correctly translated if that is indeed the problem.
User Finder-nev made some corrections to the quoted materials, so if it is a quote, that needs to be backed out as well, or at least reworded so as to be a paraphrase or interpretation of the quote. SkoreKeep ( talk) 21:59, 9 March 2021 (UTC)
A very controversial question about stages! After the well-known book “Brighter than a Thousand Suns”, written by R. Jung in 1958 based on the results of his investigation of the Manhattan Project, “dirty” thermonuclear munitions became commonly called FFF (Fission-Fusion-Fission) or three-stage (three-stage, or three-phase). However, this term is not correct. Almost all "FFF" refer to two-stage (two-phase) and differ only in the material of the tamper, which in "pure" FF (Fission-Fusion) ammunition can be made of non-fissile material (lead, tungsten, etc.), and in FFF (Fission-Fusion-Fission) from fissile material (uranium 238, thorium 232, or uranium 235, or plutonium 239, etc.). In multi-stage thermonuclear weapons, each stage is a complete separate nuclear or thermonuclear stage. In three-stage thermonuclear munitions, each stage is 3 separate nuclear and/or thermonuclear stages (charges). Usually in three-stage thermonuclear munitions, the first stage is a fission nuclear charge that emits X-ray radiation, which serves for the 2nd (small) fusion and 3rd (large fusion) stage radiation implosion. The second (“small” thermonuclear) stage fires next, after stage 1, and its X-ray radiation is used for further radiation implosion of the 3rd (“large” thermonuclear) stage.
In the AN-602 ("Tsar Bomba"), the 1st stage consisted of not one, but of 2 fission charges, the 2nd stage also consisted of not one, but of 2 "small" thermonuclear charges, but these 1st and 2nd stages were located symmetrically on both sides of the 3rd ("large" main thermonuclear) stage located in the center (the so-called "bifilar" scheme) for the AN-602 ("Tsar Bomba").
In the USSR, except for the RDS-202 and AN-602 ("Tsar Bomba"), such a scheme was never used again.
Finder-nev ( talk) 01:09, 16 April 2021 (UTC)
There are errors in the article that lead to confusion with the stages. Quote:
The test of such a complete three-stage 100 Mt bomb was rejected due to the extremely high level of radioactive contamination that would be caused by the fission reaction of large quantities of uranium-238 fission.[40] During the test, the bomb was used in a two-stage version. A. D. Sakharov, suggested using nuclear passive material instead of the uranium-238 in the secondary bomb module, which reduced the bomb's energy to 50 Mt, and, in addition to reducing the amount of radioactive fission products, avoided the fireball's contact with the Earth's surface, thus eliminating radioactive contamination of the soil and the distribution of large amounts of fallout into the atmosphere.[16]
In fact, the AN-602 ("Tsar Bomba") was not 2-stage, but 3-stage, only in the "dirty" 100 Mt version in stage 3, fissile material was used as a tamper - uranium-238 or natural uranium, and in In the “clean” 50 Mt version, a non-fissile material, lead, was used as a tamper.
PS: I myself have introduced some confusion into the discussion. I ask English-speaking editors to correct this error. -- Finder-nev ( talk) 16:51, 11 February 2022 (UTC)

Quote: Better source required | reason = Unable to verify the source. It is not known what this website is or who its author is. The "Bifilar" scheme does not make sense and will require two primary stages, as well as two sets of secondary ones. The use of two primary colors on each side was suggested as implausible during the Progressive event and should not be necessary. Date = March 2021

This text received from the participant of the event and his direct observer.
For the radiation implosion of such a large secondary (unit, block), module (a thermonuclear charge with a power of 50 megatons in TNT equivalent, the diameter of the main fusion unit was about 2 meters) a very high X-ray power is needed, which could only be produced by 2 thermonuclear charges (primary modules), for uniform implosion placed with on two opposite sides of the secondary module (i.e. symmetrically). Why exactly "thermonuclear" and not "nuclear" ones?
1). It doesn't matter which charge, nuclear or thermonuclear, is the source of X-rays for the secondary module. It is only important that this radiation is sufficient for effective radiation implosion of the used secondary module.
2). Nuclear charges have an explosion power, even with deuterium-tritium amplification, only a few tens of kilotons in TNT equivalent. (Even RDS-6s ("puff"), and even then had an explosion power of only 400 kilotons in TNT equivalent). And for effective radiation implosion of the Tsar Bomba secondary module, a design power of 2 x 750 kilotons in TNT equivalent was needed, which is about 10 times more than the "nuclear" charges could produce. Therefore, it was precisely "thermonuclear" charges that were used. In 3 authoritative sources of information it is written (links to which are given below) that 2 thermonuclear charges were used as the first stage of the bomb, and not one nuclear:

The developed nuclear charges did not satisfy this condition, and therefore, as a primary source of" super-powerful charge "A previously developed two-stage thermonuclear charge with a relatively low energy release was used.

A powerful thermonuclear charge was made according to a" bifilar "scheme: for radiation implosion of the main thermonuclear block, two thermonuclear charges were placed on both sides (front and back) to ensure synchronous (with a time difference of no more than 0.1 microseconds) ignition of thermonuclear fuel. KB-25 (VNIIA) has modified a serial block of automatic detonation for this charge».
The RDS-202 used 2 thermonuclear charges (the so-called "bifilar" scheme), which was later used to create the RN-602 ("Tsar" of the bomb). Links to 2 sources of information:

Hi all Wiki Authors,
With reference to the following sentence, in the second paragraph under the section 'Project Goals':
As an expression of the concept of nuclear deterrence adopted during the leadership of Georgy Malenkov and Nikita Khrushchev, the actual strategic situation in consideration to this concept, for the Soviet Union, as a consequence of the disequilibrium with regards to the Soviet Union vis-à-vis America's nuclear weapons possessions, to the favour of the latter, was that the creation of Tsar Bomba represented a necessitated bluff.
Appears to be an overly long and nonsensical way of saying the Soviet Union chose to go bigger to challenge the USA's more accurate deployment. I was going to change it to something I considered a little clearer, but after reading some of the conversations on how the English language should be structured in this thread, realised I was way out of my league on correct vocabulary. Any thoughts...? — Preceding unsigned comment added by 203.221.243.232 ( talk) 23:09, 13 November 2021 (UTC)
convey the same meaning more clearly? JezGrove ( talk) 23:42, 13 November 2021 (UTC)Given the Soviet Union's actual strategic disadvantage vis-à-vis America's nuclear weapons possessions, foreign policy and propaganda considerations during the leaderships of Georgy Malenkov and Nikita Khrushchev made a response to the perceived US nuclear blackmail imperative. The creation of the Tsar Bomba represented a necessitated bluff in order to maintain the concept of nuclear deterrence.
Quote:
The detonation was intended to be secret, but was detected by United States intelligence agencies, via a KC-135A aircraft (Operation SpeedLight)[11]
The fact that the explosion was secret is not true, since the USSR announced the upcoming test in advance. Criticism of the upcoming test followed at the UN, and in particular from the United States, due to the expected contamination of planet Earth with radionuclides. However, the US did not know the exact time of the upcoming test. -- Finder-nev ( talk) 17:14, 11 February 2022 (UTC)
The arcticle says that "A secret U.S. reconnaissance aircraft [...] [had] its antiradiation paint scorched. It doesn't explain what "antiradiation paint" is? And a quick search also doesn't reveal much. And the sources also doesn't seem to mention anything like that? Remove or change or provide an explanation? PS: It could mean "EMR/EMF Shielding Paint" but that isn't mentionend? CityScraper ( talk) 20:59, 25 February 2022 (UTC)
That announcement was in error, as the US had in fact tested five times under Operation Nougat ....

Not Done: The "See also" list was way too long, and had several unrelated links in. I trimmed it, and removed references to other countries, except the similarly large US test, which is the second largest by MT. Fbifriday ( talk) 16:00, 10 July 2022 (UTC)
Might these be worth mentioning in the article? Or even having articles of their own? Seems there has been recent evidence that the USA developed designs as large as 100 Megatons following the Tsar Bomba test in the event that the Soviets violated the Partial Test Ban in the 1960s, likely having to do with Flashback. https://www.aerospaceprojectsreview.com/blog/?p=3266 https://theaviationgeekclub.com/the-story-of-the-b-52-stratofortress-that-carried-the-flashback-test-vehicle-the-nuclear-bomb-bigger-than-the-soviet-tsar-bomba/ 2603:8001:9C01:F7DD:A906:37DF:C076:28D0 ( talk) 15:49, 9 September 2022 (UTC)

There are some discrepancies introduced by this reference. It's cited as a source for claims M & N in the article.
Claim M states that the flare was visible at a distance of 1000km and that it was visible from Alaska. Small problem, Alaska is 4000km from Novaya Zemlya.
I have tried to find either this author or the source on Google Scholar but the only K. A. Chernyshev I can find publishes in the field of Chemical Physics, not Nuclear Physics. The source itself cannot be found. 2A02:C7C:5841:6900:D5D6:63B8:4C1E:CFB2 ( talk) 01:00, 30 May 2024 (UTC)
